The retina is one of the most energetically expensive tissues known to science. And yet, birds’ retinas manage without a key energy-saving tool: oxygen. New research explores how.

The bird retina is one of the most energetically expensive tissues in the animal kingdom, yet it doesn’t use the energy advantage of oxygen. New research finally explains how this is possible.

“Evolution is not really like an inventor; it acts more like a tinkerer. . . . It takes parts that have existed long before, and it recombines, reinvents, and reshapes.”— Karthik Shekhar, biologist at UC Berkeley

Gecko hearts (here the ventricle) can regenerate! Proud to have been part of this @vickaryouslab.bsky.social study led by Kathy, which looked at function: ultrasound for all and pressure volume loops at final time point, and structure: histology, and transcription over 100d after cryo injury

We know many fish and amphibians can regenerate the heart. How about reptiles? A landmark paper from @vickaryouslab.bsky.social to fill this gap. Glad to be a part of this study. @isrbio.bsky.social @evodevopanam.bsky.social @socdevbio.bsky.social www.nature.com/articles/s41...

What is the primary stress hormone in the axolotl? Well turns out they do both cortisol (like fish) and cortocosterone (like most amphibians). And use them under different stressor and with different dynamics. Paper #blusci #axolotl rdcu.be/e6pzr

The adrenal stress response involves distinct dynamics of both cortisol and corticosterone in the axolotl salamander

Lab Animal - This study examines adrenal stress responses and injury signals in axolotl, showing that corticosterone dominates after amputation, while cortisol, which rises with handling stress, is...

Bird's eye view: How do birds' inner retinae work engergetically if they don't have pre-retinal blood vessels? What does the pecten do?
